I'm a programmer student from Hungary. My thesis is about Lego NXT. My hardware independent code is ready, but i still have a lot of problem with controlling the machine via BT. I totally reinstalled the applications, updated drivers and firmware. But sometimes even the official IDE failes to download the programs via BT. And it's very strange, that i have 2 ports defined for NXT ( 3 input port (?),8 output port (?) ): (Sorry for localized Windows)

I always try restarting the NXT, sometimes the pc. Sometimes it works, sometimes not. What's more, the NXT always wants a code even when i disable it in the windows. More frustrating when windows forgets my NXT, and i need to make the connection again. Which in the most cases won't work.
To tell the truth, i can't use it for real programming work. I have 1 month to finish my thesis. Please help me, if u can.
(I have Windows XP sp2, latest driver, 1.4 firmware. For Java latest RXTX, Eclipse)
